Inclusive neutrino scattering in 12C:: Implications for νμ to νe oscillations

We study inclusive nu(e) and nu(mu) cross sections in C-12 in a theory that takes into account significant nuclear renormalization of strengths. Our calculation is in excellent agreement with the measured inclusive muon capture rate and the flux-averaged nu(e) cross section, but overestimates the flux-averaged nu(mu) inclusive cross section. These reactions are of crucial relevance to the issue of possible nu(mu) to nu(e) oscillations. We also calculate the flux-averaged cross sections in C-13 and Al-27, which are found to be consistent with the available experimental result. [S0556-2813(98)04605-6].
